[Study of persistence of low virulent strain of Toxoplasma gondii on in vivo model].

Aim: To study virulence of Toxoplasma gondii strain isolated from pathologicoanatomic brain tissue of HIV-infected patients on in vivo model as well as immune response to the pathogen in immunocompetent animals and in animals with cyclophosphamide-induced areactivity.

Materials And Methods: Groups of immunocompetent and immunodeficient mice were inoculated with cysts of T. gondii obtained from brain tissues of deceased HIV-infected patients.
